When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Marble stone chemical formula.
Limestone chemical name calcium carbonate chemical formula caco3 marble is in general terms metamorphosed limestone mostly composed of recrystallised carbonate minerals.
The only difference between limestone and marble is the crystalline structure.
The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization.
Chalk is a soft white porous sedim.
In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
So the bulk of marble is just caco3.
It is the ideal alternative to traditional polishing of marble and natural stone surfaces in difficult areas such as corners edges angles touch ups etc.

Limestone crystals are much smaller than that of marble and limestone is much more porous.
Marble is made of calcium carbonate caco3 which is also what limestone is made from.
Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
Not for floors and walls.
Solvent formula coats and penetrates for long lasting shine on exterior and interior surfaces function protects and polishes the treated surfaces.
Stone surface material may be lost all over or only in spots that are more reactive.
Marble is commonly used for sculpture and as a building material.
